InnoDB table, where all selected columns
                  belong to the same unique index key, returns
                  incorrect results

Server executes some queries via QUICK_GROUP_MIN_MAX_SELECT
(MIN/MAX optimization for queries with GROUP BY or DISTINCT
clause) and that optimization implies loose index scan, so all
grouping is done by the QUICK_GROUP_MIN_MAX_SELECT::get_next
method.

The server does not set the precomputed_group_by flag for some
QUICK_GROUP_MIN_MAX_SELECT queries and duplicates grouping by
call to the end_send_group function.

Fix: when the test_if_skip_sort_order function selects loose 
index scan as a best way to satisfy an ORDER BY/GROUP BY type
of query, the precomputed_group_by flag has been set to use 
end_send/end_write functions instead of end_send_group/
end_write_group functions.

      
Bug#35658 (An empty binary value leads to mysqld crash)
        
Before this fix, the following token
  b''
caused the parser to crash when reading the binary value from the empty string.
The crash was caused by:
  ptr+= max_length - 1;
because max_length is unsigned and was 0, causing an overflow.
        
With this fix, an empty binary literal b'' is parsed as a binary value 0,
in Item_bin_string.

Bug#35480: BOM detection code crashes mysql CLI with zero-sized input
      
MySQL client crashed if no input was passed to it.

Bug#33812: mysql client incorrectly parsing DELIMITER
      
Remove unnecessary and incorrect code that tried
to pull delimiter commands out of the middle of
statements.

            as a commentary

mysql client has been modified to interpret EOL after
standalone -- commentary strings like whitespace
character (according to
http://dev.mysql.com/doc/refman/5.0/en/ansi-diff-comments.html)

Remove unnecessary and incorrect code that tried
to pull delimiter commands out of the middle of
statements.

                        
      The crash appeared to be a result of allocating an instance of Discrete_interval 
      automatically that that was referred in out-of-declaration scope.
                        
      Fixed with correcting backing up and restoring scheme of
      auto_inc_intervals_forced, introduced by bug#33029, by means of shallow copying;
      added simulation code that forces executing those fixes of the former bug that
      targeted at master-and-slave having incompatible bug#33029-prone versions.

Another problem is that the backtrace facility wasn't being
enabled for non-Linux targets even if the target OS has the
backtrace functions. Also, the stacktrace functions inside
mysqltest were being used without proper checks for their
presence in the build.

                  replicated correctly between machines with
                  mixed endiannes

On a slow environment like valgrind the test is vulnerable
because it does not check if slave has stopped at time
of the new session is requested `start slave;' -- disabling
test till it is fixed.

ha_innodb.so was incorrectly installed in the lib/mysql
directory rather than in lib/mysql/plugin.

2. Skip tests which suffer from bug
   37456 funcs_1: Several tests crash when used
                  with embedded server
3. Minor cleanup in some tests

The problem was that when a embedded linked version of mysqltest
crashed there was no way to obtain a stack trace if no core file
is available. Another problem is that the embedded version of
libmysql was not behaving (crash) the same as the non-embedded with
respect to sending commands to a explicitly closed connection.

The solution is to generate a mysqltest's stack trace on crash
and to enable "reconnect" if the connection handle was explicitly
closed so the behavior matches the non-embedded one.

This change was committed to the 5.1.25 release clone, but never
made it to the mysql-5.1 BK tree.  I'm committing it to mysql-5.1
bzr now.

make_binary_distribution.sh got clobbered by the 5.0 version during a merge.
This caused a few packaging problems, including message files put in the wrong
place and some missing files.  Fix is just to revert back to the 5.1 version
from before the merge.

This change was made in the 5.1.25 release clone in BK, but never made it to the main mysql-5.1 BK tree.  I am adding it to mysql-5.1 bzr.

The problem was that when comparing tables for a possible
fast alter table, the comparison was being performed using
the parsed information and not the final definition.
      
The solution is to use the possible final table layout to
compare if a fast alter is possible or not.

returns erroneous results

Used the wrong function when fixing 30480 which lead to
no stop on end_key resulting in duplicate results from index scan

Includes test cases for the duplicates 37327 and 37329,
Duplicate rows and bad performance/High Handler_read_next values
